Cytotoxic activity of orsellinates.
The series of 2,4-dihydroxy-6-methylbenzoates 2-10 (methyl to hexyl orsellinates) prepared by alcoholysis of lecanoric acid (1)--a natural product from the lichen Parmotrema tinctorum (Nyl.) Hale - was submitted to the brine shrimp lethality test (BST), which was also performed for 2,4-dihydroxy-6-methylbenzoic acid (11) (orsellinic acid) and the derivative ethyl-2-hydroxy-4-methoxy-6-methylben...
متن کاملIn vitro antitumour activity of orsellinates.
Lichen phenolic compounds exhibit antioxidant, antimicrobial, antiproliferative, and cytotoxic activities. The purpose of this study was to evaluate the anticancer activity of lecanoric acid, a secondary metabolite of the lichen Parmotrema tinctorum, and its derivatives, orsellinates, obtained by structural modification. A cytotoxicity assay was carried out in vitro with sulforhodamine B (SRB) ...
متن کاملAntibacterial activity of Fe3O4 nanoparticles
Antibacterial activity of Fe3O4 nanoparticles was investigated in three microorganisms including P. aeruginosa, E. Coli and Staphylococcus aureus. Fe3O4 nanoparticles were synthesized by chemical precipitation method (20 nm). The Fe3O4 nanoparticles antibacterial effect against Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus were studied by the culture method. First of all, e...
